UNF Thread

The external diameter of the Amecoil thread insert is greater than that of the tapped hole. Due to its strong adherence to the tapped hole, it is practically impossible to loosen once it has been fitted.

Regular load distribution

For about 50% of traditional joints using screws, stress is concentrated on the first inserts. The Amecoil thread insert makes it possible to distribute tensions and loads along the length of the screw. Using its elasticity, it forms a "seal" between the screw and the nut and corrects pitch ad angle differences between the threading and the tapping.

Reduces bosses

The Amecoil reduces the weight and bulk of the parts. Due to its features, it requires less space than other systems (one-piece inserts, sleeve coupling...) and reduces bosses in particular in tappings made of low resistance material.

Resistant to corrosion and other attacks

The Amecoil thread insert eliminates tapping deterioration due to tearing, vibrations, fatigue, seizure or corrosion, and remains resistant to high temperatures.

Resistant to premature wear

Practically impossible to wear, it makes it possible to obtain tappings "for life" in parts made of low resistance material. This important feature means that, even after it has been used many times, it always complies with the most rigorous standards.

Simplifies locking systems

With the Amecoil self-locking system time and money are saved by doing away with pins, lock-nuts, lock-washers, etc.
